Receiving NOAA Weather Satellite Images at rtl-sdr.Everyday multiple NOAA weather satellites pass above you.So far I have not found a proper solution for this problem.
#Wxtoimg rtl sdr free#
Still the free version seems sufficient.Īlso WXtoIMG often does not recognize the satellite pass the image comes from. As such there are various workarounds which are based on setting the system time to 2016, starting WXtoImg and changing the year back to 2017.

The license key on the webpage will seemingly “not work” as it’s limited for use in 2016.

While development has been stopped the pro version has been made free.

WXtoImg seems to be a really piece of software for working with the received images.
Having the antenna in the attic, under the roof, results in bad noise when its raining. I’m located on the side of a mountain-range as such my reception towards the south is really bad. Depending on the exact location of your antenna you might and will have certain reception issues. Helical Quad Antenna for Weather Satellites at įiles, Images and Recordings The first one ever - NOAA 19, 20170624-1545. QFH antenna for the weather satellite band at G4ILO’s Shack. As expected the tiling is a good shield, especially when it’s wet (rain reduces reception to zero). While the time frames in which I received data from the satellites rose significantly, the overall signal quality dropped. All in all resulting in a rather s***ty place to put an antenna.Īfter a few days I shifted the antenna into the attic, ~4th floor. 
One side was partially covered by the mountain range the house is one, one by the house itself, the third partially by our neighbours house. Days of fiddling with the wires and trying to get them into shape Antenna Positioningīefore setting up the antenna in the attic I gave it multiple test runs in the garden at rather low elevation.
Do the soldering in the center and attach feed wire. Add 45°.60° degree bend to last few cm. Mark the necessary length of wire for top arm. Building the antenna was rather straight forward: The actual conductor is 10mm² solid core wire (Erdungsleitung). I used a 40mm pipe for the center rod and 16mm cable duct for the “arms”. Click the little downwards pointing arrow in the top right corner above the map -> Configure : Select the satellites you’d like to track.Īfter doing a bit of reading decided to give building a Quadrifilar Helix (QFH) Antenna a try. Google Maps will probably be the easiest way to find out the proper coordinates. Edit -> Preferences -> General -> Ground Stations : Configure where you have your antenna. It will also predict time frames in which programmed groundstations are in line of site. GPREDICT will fetch satellite orbits from CelesTrak and visualizes them on a map. The easiest approach seems to be using GPREDICT which can be found on github. Reception of data is only possible, when the groundstation has line of sight with the satellite, as such you will want to do some tracking. Have a look at the “Enhancements” menu for all the different options. It also uses reference data from CelesTrak to create a map overlay over the satellite image itself. You can simply start it from the command line by running WXtoImg -G. Make sure to use WAV (Microsoft) signed 16-bit PCMįor decoding the received data I’ve been using WXtoImg. Set “Project Rate (Hz)” to 11025 (bottom left corner of the screen). As such open the file and perform the following steps: 
Getting the Image Preparationsīefore working with the recording, a bit of prep work using Audacity is necessary. When the satellite comes into range, simply hit the record button. Check the Files and Recordings section below for references.
Filter width: User (42k) - set by adjust the filter width on screenĭuring reception one can perfectly hear the data transmission and watch it in the waterfall plot. Main configuration (Configure I/O devices screen). While writing this I’m using a NooElec NESDR Smart and GQRX. The data transmitted by the satellites can easily be received using your favourite flavour of RTL-SDR or other SDR hardware. They basically continiuously stream pictures back to earth using APT - Automatic Picture Transmission. They currently have three satellites in orbit which regularly pass over Europe: NOAA 15, NOAA 18, NOAA 19. NOAA is the US National Oceanic and Atmospheric Administration.
